1d845319dc dt-bindings: mfd: Dual licensing for st,stpmic1 bindings 
Change include/dt-bindings/mfd/st,stpmic1.h license model from GPLv2.0
only to dual GPLv2.0 or BSD-2-Clause. I have every legitimacy to request
this change on behalf of STMicroelectronics. This change clarifies that
this DT binding header file can be shared with software components as
bootloaders and OSes that are not published under GPLv2 terms.

In CC are all the contributors to this header file.

ddeeca1300 mfd: intel_soc_pmic_crc: Use PWM_LOOKUP_WITH_MODULE() for the PWM lookup 
The primary use of the CRC PMIC's PWM is for LCD panel backlight
control by the i915 driver.

Due to its complexity the probe() function of the i915 driver does not
support -EPROBE_DEFER handling. So far the pwm-crc driver must be built
into the kernel to ensure that the pwm_get() done by the i915 driver
succeeds at once (rather then returning -EPROBE_DEFER).

But the PWM core can load the module from pwm_get() if a module-name is
provided in the pwm_lookup associated with the consumer device.

Switch to using PWM_LOOKUP_WITH_MODULE() for the lookup added for
the Intel integrated GPU, so that the PWM core can load the module from
pwm_get() as needed allowing the pwm-crc driver to be safely built as
module.

This has been successfully tested on an Asus T100TAM with pwm-crc
build as a module.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

While add it, also remove commas after the sentinel entries.

914089db30 input: Add onkey driver for Marvell 88PM886 PMIC 
Marvell 88PM886 PMIC provides onkey among other things. Add client
driver to handle it. The driver currently only provides a basic support
omitting additional functions found in the vendor version, such as long
onkey and GPIO integration.

Introduce driver for WDG block on ROHM BD96801 scalable PMIC.

This driver only supports watchdog with I2C feeding and delayed
response detection. Whether the watchdog toggles PRSTB pin or
just causes an interrupt can be configured via device-tree.

The BD96801 PMIC HW supports also window watchdog (too early
feeding detection) and Q&A mode. These are not supported by
this driver.

a9b7ce28fd regulator: bd96801: ROHM BD96801 PMIC regulators 
The ROHM BD96801 "Scalable PMIC" is an automotive grade PMIC which can
scale to different applications by allowing chaining of PMICs. The PMIC
also supports various protection features which can be configured either
to fire IRQs - or to shut down power outputs when failure is detected.

The driver implements basic voltage control and sending error
notifications.

NOTE:
The driver does not support doing configuration which require the PMIC
to be in STBY state. The omitted feature set includes setting safety
limit values, changing LDO voltages and controlling enable state for
some regulators.
Also, the ERRB IRQ is not handled.
